+* Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device
+
+PRCM is an MFD device exposing several Power Management related devices
+(like clks and reset controllers).
+
+Required properties:
+ - compatible: "allwinner,sun6i-a31-prcm"
+ - reg: The PRCM registers range
+
+The prcm node may contain several subdevices definitions:
+ - see Documentation/devicetree/clk/sunxi.txt for clock devices
+ - see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset
+ controller devices
+
+
+Example:
+
+ prcm: prcm@01f01400 {
+ compatible = "allwinner,sun6i-a31-prcm";
+ reg = <0x01f01400 0x200>;
+
+ /* Put subdevices here */
+ ar100: ar100_clk {
+ compatible = "allwinner,sun6i-a31-ar100-clk";
+ #clock-cells = <0>;
+ clocks = <&osc32k>, <&osc24M>, <&pll6>, <&pll6>;
+ };
+
+ ahb0: ahb0_clk {
+ compatible = "fixed-factor-clock";
+ #clock-cells = <0>;
+ clock-div = <1>;
+ clock-mult = <1>;
+ clocks = <&ar100_div>;
+ clock-output-names = "ahb0";
+ };
+
+ apb0: apb0_clk {
+ compatible = "allwinner,sun6i-a31-apb0-clk";
+ #clock-cells = <0>;
+ clocks = <&ahb0>;
+ clock-output-names = "apb0";
+ };
+
+ apb0_gates: apb0_gates_clk {
+ compatible = "allwinner,sun6i-a31-apb0-gates-clk";
+ #clock-cells = <1>;
+ clocks = <&apb0>;
+ clock-output-names = "apb0_pio", "apb0_ir",
+ "apb0_timer01", "apb0_p2wi",
+ "apb0_uart", "apb0_1wire",
+ "apb0_i2c";
+ };
+
+ apb0_rst: apb0_rst {
+ compatible = "allwinner,sun6i-a31-clock-reset";
+ #reset-cells = <1>;
+ };
+ };
